Found out about this at the CBA forums. Problem is that my 1891 argie carbine slugs out at .313" also have a long branch sporter that also slugs out at around .315" My lyman 314299 as cast diameter is .314" so I would like to get a bullet mold that would cast large enough so as to be used in both rifles. The long branch sporter has a two groove bbl and has basically no wear that i can see. Is the 316299 a group buy mold?. Thanks, Frank
